Pelletizing - Wikipedia

After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota's iron ore mining industry. To make these pellets, the hard taconite ore is blasted and then ground down with water to a fine powder. The fine iron rich particles, mostly of magnetite are extracted from the powder by use of magnetism. The concentrate (the wet taconite powder) is rolled ...

Taconite - Wikipedia

Creating steel from low-grade iron ore requires a long process of mining, crushing, separating, concentrating, mixing, pelletizing, and shipping. The process of mining low -grade iron ore, or taconite, requires massive resources. Heavy industrial mining equipment, expansive mines, and a skilled labor pool are all required.

Iron Ore Pellet - an overview | ScienceDirect Topics

The Fastmet is a continuous process which basically consists of a rotary hearth furnace where one or two layers of self-reducing iron ore pellets are placed. These self-reducing pellets are made from a mixture of iron ore concentrate, reductor (coal or coke), and binder. Unlike the other processes previously described, the Fastmet process uses a solid instead of a gas to reduce the iron oxide ...
